There were retrospectively evaluated the data collected from 236 patients: with ovarian tumors (n = 63), cervical cancer (n = 51), breast tumors (n = 64), malignant neoplasms of the uterine body (n = 58). The control group consisted of 50 women without malignant neoplasms. The analysis of homocysteine (HC) concentration, the frequency of polymorphisms of the genes encoding folate cycle enzymes MTHFR C677T, MTHFR A1298C, MTRR A66G, MTR A2756G as well as the rate of thrombotic complications was carried out. A risk of blood HC level-related thrombotic complications was assessed.</p></sec><sec><title>Results</title><p>Results. Plasma HC concentration comprised ≥ 22 μmol/l in 30.5 % of patients. Thrombotic complications within one year after discharge from the hospital were developed in 15.3 % cases. The risk of thrombotic complications turned out to be higher in patients with elevated plasma HC level (≥ 22 μmol/l) (odds ratio = 2.99; 95 % confidence interval = 1.11–8.08). No significantly increased prevalence of polymorphisms in the genes encoding folate cycle enzymes among female cancer patients was detected.</p></sec><sec><title>Conclusion</title><p>Conclusion. Monitoring HC level in female cancer patients contributes separately to predict a likelihood of thrombotic complications. Prescribing drugs that reduce HC level (folic acid) and monitoring its concentration in female cancer patients during therapy, including chemotherapy, can potentially lower an incidence of thrombotic complications.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Гипергомоцистеинемия (ГГЦ) является одним из звеньев патогенеза тромботических осложнений у онкогинекологических пациенток.</p></sec><sec><title>Цель</title><p>Цель: оценка вклада ГГЦ в развитие тромботических осложнений у пациенток со злокачественными новообразованиями женских половых органов и молочной железы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Выполнена ретроспективная оценка данных 236 пациенток: с опухолями яичников (n = 63), раком шейки матки (n = 51), опухолями молочных желез (n = 64), злокачественными новообразованиями тела матки (n = 58). Контрольную группу составили 50 женщин без злокачественных новообразований. Проведен анализ концентрации гомоцистеина (ГЦ), частоты полиморфизмов генов ферментов фолатного цикла MTHFR C677T, MTHFR A1298C, MTRR A66G, MTR A2756G, частоты тромботических осложнений. Проведена оценка риска тромботических осложнений в зависимости от концентрации ГЦ в крови.</p></sec><sec><title>Результаты</title><p>Результаты. Концентрация ГЦ в плазме крови составила ≥ 22 мкмоль/л у 30,5 % пациенток. Тромботические осложнения в течение 1 года после выписки из стационара развились у 15,3 %. Риск тромботических осложнений оказался выше у пациенток с высоким уровнем ГЦ (≥ 22 мкмоль/л) в плазме крови (отношение шансов = 2,99; 95 % доверительный интервал = 1,11–8,08). Достоверного увеличения частоты встречаемости полиморфизмов генов ферментов фолатного цикла среди онкогинекологических пациенток выявлено не было.</p></sec><sec><title>Заключение</title><p>Заключение. Мониторинг содержания ГЦ у онкогинекологических пациенток вносит свой вклад в прогнозирование вероятности тромботических осложнений. Назначение препаратов, снижающих уровень ГЦ (фолиевая кислота), и проведение мониторинга его концентрации у онкогинекологических пациенток на фоне терапии, в том числе и химиотерапии, потенциально способно снизить частоту развития тромботических осложнений.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоз</kwd><kwd>гомоцистеин</kwd><kwd>ГЦ</kwd><kwd>гипергомоцистеинемия</kwd><kwd>ГГЦ</kwd><kwd>онкотромбозы</kwd><kwd>фолиевая кислота</kwd><kwd>фолатный цикл</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thrombosis</kwd><kwd>homocysteine</kwd><kwd>HC</kwd><kwd>hyperhomocysteinemia</kwd><kwd>HHC</kwd><kwd>oncothrombosis</kwd><kwd>folic acid</kwd><kwd>folate cycle</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alcalay A., Wun T., Khatri V. et al.
